Cheryl Cole used her first day on Twitter to wish
Cameron Diaz a happy birthday – and now it seems the star can’t get enough of the social networking site.

Cheryl Cole has been using Twitter to practise her words (PA)

The former X Factor judge finally broke her Twitter silence yesterday on the set of What To Expect When Youâre Expecting , posting: âIt’s me CC! WHERE MY SOLDIERS AT…….?!!! I can’t believe what my fingers are doing but yes I’m tweeting :-s so here goes…Xâ

She quickly followed up the post by wishing co-star and new friend Cameron Diaz a happy birthday, writing: âHappy birthday Cameron, you sexy beeeyyaatchh…Xâ

While the tweet prompted confusion in some quarters â with some even suggesting Cameron posted the message herself from Cherylâs phone â it appears Cheryl is fully set on embracing the Twitter trend.

Bemoaning her early starts on set, she wrote: âThere is NOTHING better than the smell of fresh coffee in the morning.. Esp when your call time is 4.30am 8-| …

âThat’s not even the morning. That’s the middle of the night…â

Cheryl Cole gets to grips with Twitter

But Cheryl has an even more pressing issue â the lack of emoticons on Twitter.

She told followers: âBtw I’m gutted I can’t use my little yellow men faces on here.. They help me express what I’m saying…

âI’d put the rolling eyes one here.. But he looks like this 8-|â

Speculation is now mounting as to who Cheryl will choose to follow on the social networking site â while over 200,000 people are currently following the star, the lady herself has yet to follow a single user on Twitter.

One user almost certain to get a follow is Cherylâs pal and fellow guest star on What To Expect When Youâre Expecting, Black Eyed Peas star Taboo.

He posted a photo of the pair alongside dancer Tyce Diorio on set, writing: â@cherylcole @tycediorio co working on a project in hotlanta .. I love this job !!! Great people working here.â

The trio appear as talent show judges in the film, with Cameron Diaz playing an aspiring singer who auditions for the panel.
